What We Do
For over thirty years, Lynx Software Technologies has helped customers with some of the most demanding, mission critical, system requirements to create, certify, and deploy equipment, above, on and below the surface of the earth.. Lynx for the Internet of Things (IoT): As billions of ‘things’ are connected to the internet, a new paradigm of security is required. Lynx offers real-time military-grade security products to protect the edge, the gateway and cloud devices while protecting any sensitive data as it traverses the IoT. Key Markets: Automotive, Industrial, Factory Automation, Medical and Transportation. Our LYNX MOSA.ic software framework and LynxSecure separation kernel hypervisor provide a secure foundation for this new generation of connected platforms. Lynx for Enterprise Cyber Security: To fight modern day malicious threats, security needs to be built-in rather than implemented as an afterthought. Lynx offers isolation technology that can be implemented in endpoint and cloud deployments to separate and protect critical enterprise infrastructure. This isolation technology separates sensitive information from the key attack points and denies infiltration and exfiltration attempts. Lynx for Aerospace & Defense: Lynx provides certified avionics RTOS solutions based on open standards such as POSIX, ARINC and FACE that allow reusability of certified code and systems. The FAA Reusable Software Component (RSC) has been issued to LynxOS-178. The LynxOS 7.0 RTOS and LynxSecure separation kernel technologies were designed to provide the highest levels of security without compromising performance and real-time determinism.
